Letters Patent No. 98,782, dated January 1l, 1870.

IMPROVEMENT IN COAL-LOADING- DEVICE.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, JOHN F. LOGAN, of Coal Bluffs, in the county ofWashington, and State of Pennsylvania, have invented certain new andiuseful Improvements in Devices for Loading Goal; and I do herebydeclare that the following is .a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecifica.-v

tion.

The nature of my invention consists-iu the conl struction and use ofdevices, as hereinafter described,

whereby coal or other material can bereadily loaded into boats or othermeans of transportation, without deterioration fgoln breakages intosmaller' pieces than required. l l,

In the accompanying drawings- Figure l is a side elevation of myinvention.

Figure 2, a sectional plan thereof.

Letters of reference denote parts.

A flame-work, A, of suitable construction, supports andcarries thedevices used, at lthe upper part of which, and pendent therefrom, isanordinary inclined screen, A, which may be raised or lowered by theaction of an ordinary wheeland lever, A".

The month of said screen projects over an inclined platform, B,constructed of `suitable materiahand pendent and connected tothe leversof any ordinary weighing-scale, situated above the frame A, saidplatform being provided, longitudinally, with rails, B1, of any suitableform, and attached thereto in any suitable manner.

Rising vertically from said platform B, are standards,

B2, to which is pivoted a curved arm, B3, terminating with a hook, B4,to 4which is airixed a rope or chain,

155,A attached to 'an ordinary drum and lever, B2, to which isalsoattached a counterpoise, B2, situated at the upper part of saidframe A.

By the manipulation of said wheel and lever B6, said hook B can beraised, and bythe falling of said counterpoise B7, will 4fall to itsoriginal position.

At the lower` end of said platform B, and iu line with lthe same, arerails or tracks, C, being' supported at one end by the cross-beam G,said rails being spliced together and joined together by means of theplate R and pins R', in such a manner, as each successive section ofrail can be raised and depressed, as required, into separate anddistinct planes.

Said tracks are pendentfrom frame A, by means ofthe cross-bars C2 andchains C. lhe extremities of these tracks O are furnished with across-bar, C", to which is attached a rope, C5, passing over pulleys C2,affixed in any suitable manner to frame A, the end of said cord being.fdrnished with a counterpoise, 1C", so arranged, that hy raising orlowering the same, the last section of track C will lbe raised ordepressed, which section C is also furnished, on'vthe side, with acurved catch, U", so arranged that the latch D, of a pivoted door, D, ofa coal-car, D2, will meet the same, raising said latch D, which raisesthe door D1 thereof.

Said coal-car D2 is furnished witlr ordinary wheels and axles, D3,'andruns upon before-named track C,

said car D2 being so arranged, that when resting on before-namedplatform B, the hook B4 will pass over the said coal-carD2., retainingitin its position thereon. The rear end of said car D2 is provided, inany suit able manner, with a rope or chain, E, which is attached to andencircles an ordinary drum, E1, affixed on au ordinary shaft, E2,running transversely with frame A, in which it revolves, in suitablebearings thereon; and said shaft is, furthermore, provided with awheel,E3, encircled by an ordinary clip-brake, E, connected to an ordinarycranked lever,E5, attached to frame A, at E6, by means of a bolt, E2,the lower end o f said lever E5 being connected, by a rod or chain, E",to an ordinary lever, E, pivoted'in the forward part of frame A. By themovement of the saine, said brake E4 tightens on` the wheel E2. 4 Y

Said shaft E2 isalso provided, in any suitable manner, with an ordinaryratchet-toothed wheel, F, and also with a lever, F1, carrying aspring-pawl, F2, so arranged, that by pulling over the lever l1, thepawi F2 engages in the teeth of the wheel F, which, being firmly 4attached tothe shaft E2, causes it to revolve a quarter turn or more, inratio with the distance said lever F1 is pulled over. This movementslackens the rope E, leaving the coal-car D2 supported only by the hookB4, save and except the platform B, on which :it rests. Said car is thenin position for weighing.

Said shaft E2 is also provided with an ordinary druin- I wheel, G,encircling which, and attached thereto in any suitable manner, is a ropeorchain, G, attached to an ,ordinary carriage, G2, supported b ordinarywheels and axles, G3, and rest-ing upon ra ls H, running parallel, orthereabout, with before-mentioned track C, said track H being jointed,at H1, by means of the plates B. and pins lt.

At the end of said rails H is a cross-bar, H2, to which is attached arope, H, passing upward to au ordinary wheel and lever, H", by themanipulation of which, said rails' H can be raised and depressed, asrequired.

Said car Gr2 is lled with any ordinary heavyweights.

The mode of operating with my devices is as follows, viz:

Goal being delivered from the ordinary coal-mine wagons on to the screenA, the smaller coal falls through the same, and may be carried away inordinary manner. The larger lumps of coal fall into the coal-car D2,which is resting upon the platform B, in such a manner that the hook B4passes over and rests against the door Dl of said car D2, which is alsokept in placeby the tension ofthe rope E on the drum El, said car D2being lled by the manipulation of the pawl F2 ofthe lever F1. The shaftE2 being partly revolved, the said rope E is slackened, leaving the carD2 held in posit-ion only by the hook Bf, said car being thensupported'only by said hook B, and platform B is` ready for theoperation of weighing, which being completed, said hook B4 is withdrawnfrom contact with said car D2, by the manipulation of wheel and lever B.The car D2 then runs down the track C, until the latch D, of the doorD1, meets the catch C, which lifts up said door D1, allowing the coal tofallout wherever it be required.

During the downward travel ofthe car D2, the car-l riage G2 ascends thetrack H, which, descending after the coal is removed fromthe car D2,draws up the said car D2 to its original position.

Heretofore, no provision has been made, in coalchutes or loaders, forthe altering of the incline of the tracks', which chutes, being situatedon the banks of rivers, and the stage of wat-er being low, stand highfrom the boats or other modes of transport; consequently, t-he coalbeing delivered from that height, is liable to be broken in smallpieces,besides causing excessive injury to the boats. j

Coal-loaders being-constructed according to my bewheel and lever G, ropeG, substantially as and for the purpose described and set forth.

2. The arrangement of the plat-form B, with its track B1, standards B2,hook B4, rope B5, carriage D2, screen A, in combination with the hingedtrack G, substantially as described, and for the purpose set forth.

3. In combination with thevabove, the shaft E2, carrying the drums E1and G, brake-wheel E, clip E, lever Efrod E, ratchet-wheel F, lever F1,and pawl F2, substantially as described, and for the purpose set forth.

In testimony that I claim the ibregoing' as my own,

I aliix my signature, in presence of two witnesses.
